Microchip Technology 

PIC16F913/914/916/917/946

3.5.1.8 RC7/RX/DT/SDI/SDA/SEG8

Figure 3-21 shows the diagram for this pin. The RC7

pin is configurable to function as one of the following:

• a general purpose I/O

• an asynchronous serial input

• a synchronous serial data I/O

• a SPI data input

• an I2C data I/O

• an analog output for the LCD
